The WordPress improvement staff, in a sequence of missteps, pushed out a flawed replace that made it not possible to put in new WordPress websites. They paused the replace rollout in an try to repair that replace however that created much more issues, requiring an emergency replace to repair all the issues.
Flawed WordPress 5.5.2 Security Update
The fiasco started on October 29, 2020 with a routine replace meant to deal with crucial safety points. WordPress 5.5.2 was meant to stop points like Cross Site Request Forgeries, XSS (Cross Site Scripting) assaults and extra.
Unfortunately, the replace additionally launched a bug that induced new WordPress installations to fail. This is how WordPress defined the bug:
“WordPress 5.5.2 …makes it impossible to install WordPress on a brand new website that does not have a database connection configured. This release does not affect sites where a database connection is already configured, for example, via one-click installers or an existing wp-config.php file.”
In order to repair that downside, WordPress stopped model 5.5.2 from rolling out to extra websites. And that’s when a rogue replace pushed itself out robotically.

WordPress Alpha Update Accidentally Pushed Out
WordPress put the brakes on additional updates. But whereas the WordPress staff was busy getting WordPress 5.5.three prepared to be able to repair the earlier bug, WordPress auto-updates started yet again.
But as a result of Version 5.5.2 was unavailable, the automated WordPress system chosen an Alpha model of WordPress to be downloaded and put in on October 29th. This Alpha model was not meant to be put in and contained issues.
WordPress 5.5.three Alpha Bugs
The problem with the WordPress Alpha set up was that it launched further WordPress themes and put in Akismet.
There is supposedly nothing unsuitable with these themes. But publishers who select to not delete them shall be burdened with having to maintain them up to date. Failure to replace these themes may sooner or later pose a safety threat.
According to the WordPress announcement:
“Earlier at present the auto-replace system for WordPress up to date some websites from model 5.5.2 to model 5.5.three-alpha. This was on account of an error attributable to preparations being made for the 5.5.three launch.
The 5.5.three-alpha model at this level was functionally equivalent to five.5.2 as no improvement work had been began on 5.5.three, nonetheless the next modifications might have been made:
The default “Twenty” themes put in as a part of the pre-launch package deal. The “Akismet” plugin put in as a part of the pre-launch package deal.”

An online web page, apparently for the Alpha launch, was revealed on October 29, 2020, apparently erroneously labeled as Version 5.four.three. I say erroneously as a result of WordPress 5.four was launched in March 2020 and it doesn’t make sense to go backwards from WordPress 5.5 to a 5.four model.
The seemingly faulty 5.four.three Update Page accommodates documentation that’s equivalent to the data revealed for Version 5.5.2
The newest replace, Version 5.5.three is the whole lot model 5.5.2 was meant to be, solely with out the related issues. WordPress 5.5.three fixes all the issues launched within the 5.5.2 model.
“This upkeep launch fixes a problem launched in WordPress 5.5.2 which makes it not possible to put in WordPress on a model new web site that doesn’t have a database connection configured. This launch doesn’t have an effect on websites the place a database connection is already configured, for instance, by way of one-click on installers or an present wp-config.php file.
If you aren’t on 5.5.2, or have auto-updates for minor releases disabled, please manually replace to the 5.5.three model by downloading WordPress 5.5.three or visiting Dashboard → Updates and click on “Update Now.””
What Went Wrong
The issues have been launched by the event staff as a result of there was no formal documentation on the way to cease a WordPress replace. Because of that, the WordPress staff stopped the replace in a method that opened the door for the Alpha model to start rolling out.
This problem has been addressed in order that this state of affairs received’t occur once more.
According to the official technical particulars submit:
“…that won’t be done again. Now seems like a good time to document a correct and proper way of “stopping” a launch in progress, which truthfully had not been tried earlier than. Stopping a launch is definitely fairly easy if that they had made the right change, so whereas their try was an inexpensive assumption to make, it turned out to be unsuitable.
The launch system is difficult, and attempting to do issues with it that haven’t been anticipated and documented led to sudden outcomes. This shall be improved via documentation and higher code and administration of the discharge system itself.”
